T aZZ whom it may concern:

Be it known that I, JEAN JACQUES BOUR- CART, civil engineer, of Zurich,Swiss Gonfederation, have invented Improvements in Ring-Spinning Frames;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed sheets ofdrawings, I have received German Letters Patent for said invention,dated March 19, 1880, No. 11,976, and English Letters Patent, datedDecember 2, 1880, No.

This invention relates to certain improvements in ring-spinning frames,fully describe d hereinafter, whereby to insure a regular twist,facilitate the operations, and overcome certain defects incidental toordinary constructions.

In the accompanying drawings, Figure 1 is a front elevation of part of aring-spinning frame embodying my improvements. Fig. 2 is a sideelevation, in part section on the line m, Fig. 1. Fig. 3 is a detachedsectional. elevation showing one of the spindles, supporting-rails, andring, ring support and guide, and modified form of a step, wharve, andfric- -tion-disk. Fig. 4 is an enlarged sectional two series supportedby rails G D and O and D, the rails (3 D being above and back of therails 0 D so that the rear spindles are higher than the front spindles.Each spindle turns at its lower end in a step, C", and extends throughthe upper rail and through a long tube or bolster, 0, supported by thesaid upper rail.

Upon the spindle, above the foot-step bearing, are friction disks 1) bthe lower forming part of the wharve D, and in the modified forms shownin Figs. 3 and 4 provided with a tube, m, revolving in or on a tubularextension, e, of the step. The upper friction-disk is secured to thespindle, and a washer, if, of cloth, india-rubber, or other frictionmaterial, is preferably placed between the disks. By this construction,if an excessive traction is exerted on the spindle it is able to yield alittle,because its foot is not rigidly held in its step, and theslipping of the upper disk, 1), upon the lower disk, b, permits thisplay of the spindle D, which, however, tends to return to its positioncentral with the axis of the step as soon as the traction is removed,this tendency resulting from p the rapid motion of the spindle impartedby the frictional contact of the disk b with the rapidly-revolvingdriving-wharves. The frictional connection between the spindle and thewharve also prevents too sudden movement of the spindle in starting orstopping.

As the ,wharve D has its bearing in the tubular part of the step, and asthe spindle is n t in direct contact with the tube m of the wharve, anylateral draft upon the wharve will not affect the spindle or throw itfrom its central position or increase the friction. The driving drum orcylinder F is secured to the driving-shaft X, turning in bearings uponthe frame of the machine, and one series of bands,

1), pass round the driving-cylinder and beneath a guidecylinder, D tothe wharves of the upper spindles, and another series of bands, 1), passround the driving-cylinder and beneath guiding-cylinders D D to thewharves of the lower spindles.

To the end of a loose sleeve, m on the driving-shaft is secured apulley, K, and to the shaft X is secured a pulley, K and upon the end ofthe shaft X turns an idler-pulley, K so that by shifting thedriving-belt Z onto the pulley K the cylinder may be rotated, byshifting it onto the pulley K the sleeve m is rotated without moving thecylinder,while by shifting it onto the idler-pulley the movements of allparts of the machine are arrested. The bolster G not only steadies thespindle at a point a considerable distance above its step, but alsosupports a circular block, of, which serves as a guide for a tube orcylinder, 0, carrying the usualring,t,at the upper end,and having at thelower end an annular bearing, through which the bolster passes, so thatthe said tube slides upon the said bolster and guide-block, a feather orpin, 0 upon the tube 0, extending into a vertical slot, G, in thebolster, so as to permit the said sliding movement, but prevent anyrotation of the tube. A traveler, t, is carried by each ring t, and theyarn passes through thesame to the spindle, as usual. It is requisite toimpart to each ring not only an ascending and descending movement,necessary for winding on a 7 layer of yarn, but also a varying ascendingmovement for the purpose of building up the body of the cop. Thesemovements are derived from the rotation of the drivingpulleys throughthe medium of devices which will now be described. The reciprocatingmotion of the tube Ois imparted from a cam, E,which acts upon an arm, n,projecting from a rockshaft, O, and the arm operates through the shaftand intermediate gears, E E E E, upon a shaft, 0, having a pinion, c,gearing with a rack-bar, O, at the rear side of the tube 0. WVhen thereare two series of tubes 0, there aretwo shafts, the upper shaft, 0',before referred to, and a lower shaft, 0, each of which carries apiniongearing with a rackbar upon each tube 0. The shaft 0 carries apinion, E, between which and the gears E intervenes a gear, E. The gearE is carried by a sleeve, 0, turning loosely upon the shaft 0, andcarrying a worm-wheel, E.

I To the rock-shaft O is secured a frame, E, from which projects an arm,E", and which carries a shaft, E having on it a worm, e, and aratchetwheel, E the worm gearing with the wheel E, and theratchet'engaging with a pawl, 6 hung to the frame of the machine. (SeeFig. 1.) As the worm locks with the worm-wheel,the vibration of the aimn will carry with it the gear E although the latter is loose on theshaft 0, because the worm engages the teeth of the worm-wheel, so thatas the arm n is lifted by the rotation of the cam E in the direction ofits arrow, Fig. 2, both of the shafts O and 0 will be turned so as tocarry downward the ring-tubes O, which motion will lay the yarn on thecop, and as the shoulder w of the cam passes from beneath the end of thearm n, and the latter swings downward, the ring-tubes will rise morerapidly than they descended,thereby carrying the yarn spirally over thelast layer to the top of the cop. As each layer of yarn should be laidabove that below it in the manner required in the usual building up of acop, it is necessary that the ring shall be lifted at each movement alittle farther than upon the proceeding movement and shall descend to aslightly less extent. This movementis effected through the mediumofthesleeve 0, worm e", worm-wheel E", ratchetwheel E and pawl 6 The upwardrocking movement of the frame E brings the ratchet-- wheel E against thepawl, which causes the wheel and worm to be rotated to a slight extent,thereby rotating the wheel E, and, through the intermediate gears, theshafts 0 and 0 sufficiently to lift the tubes slightly in excess of thelifting effected by the regular rocking movement of the shaft, thedescent being correspondingly limited. The extent to which this regularupward feed of the rings is effected may of course be regulated bysetting the pawl so as to secure a greater or less movement of theratchetwheel. The rapid downward movement of the arm n is facilitatedand insured by a spring, e, connected at the lower end to the frame ofthe machine and at the upper end to the end of the arm E". Each pinion cbears on a collar, 0 and is secured to a loose sleeve, 0 which turnsloosely upon the pinion-shaft, and has a serrated end adapted to theserrated end of a second sleeve, 0*, which turns with but slides uponthe shaft, and is carried toward the sleeve 0 by the action of a spring,0, these devices constituting a clutch, which, under ordinarycircumstances, will insure the rotation of the pinion c with the shaft,but which will permit the said pinion c to rotate when an excessivepressure is brought to bear upon the tube 0 to carry the latterdownward. Each ring is thus rendered independently adjustable, so thataccess may at any time be had to any one of the cops without interferingwith the position of its ring in respect to the others, while the variedrise and fall and uniform gradual ascent of all the rings are effected.

In continuous spinning it is very desirable that the movements of thedrawing-rollers shall be arrested at certain periods. Inasmuch as thewinding on is effected during a continuous delivery of the yarn, therewill be formed at the end of the rise of the ring an accumulation ofyarn on the end of the cop that is,tw0 or morelayers ofyarn will bewound on the same spot. This is prevented if the delivery is stopped foran instant when the ring completes its rise.

The intermittent action of the drawing-rolls necessary to secure theseresults is effected by throwing the drawing-roller shaft temporarily outof gear or connection with the other de-' vices. One mode of effectingthis will now be described: A vertical shaft, 7, is provided with aworm-wheel, 9 which gears with a worm, 9, upon the sleeve m and abevelpinion, a, upon the shaft y meshes with a bevel-wheel, E upon theshaft a of the cam E, so that the said cam is rotated from the rotationof the sleeve m which is carried around with the pulley K. Thedrawingroller shaft 9' is driven from the shaft 3/ through the medium ofa short shaft, 9 bevel-gears g g g g, a shaft, 9, and a clutch devicewhereby the shaft y may be thrown into and out of connection with theshaft 9 As shown, the clutch device consists of a serrated enlargement,a, of the shaft 9, and a serrated enlargement, 3 on a sleeve, 3/, whichslides upon but turns with the shafti and is grooved to receive theforks of a shifting-lever, y, pivoted to the frame of the machine andconnected to a rod, y which has at the lower end an elongated slot oreye, 4;, receiving a pin, 3 projecting from the arm E The pin and theslot 1) are so arranged that as the arm E approaches the limit of itsmovement in either direction the pin will be brought against one or theother end of the slot, and the clutchsleeve 3 will be thrown into or outof connection with the other portion of the clutch device. Thus as thering completes its ascent the pin y is brought against the lower end ofthe slot, and the clutch-sleeve is drawn down, so that the feed of theyarn is arrested. The arrest of the action of the drawing-rollers at thetime that the ring reaches the termination of its upper movementprevents the accumulation of the yarn at the point of the cop. Themoment the rings begin to descend the pin 3 begins to rise, and acounter weight, W on the end of the shiftinglever lifts theclutch-sleeve, so as'to throw the shafts y and 9 into gear, and startthe action of the drawing-rollers.

In machines of ordinary construction the drawing-rollers, spindles, andtravelers are simultaneously put in motion, the result being that manyyarns are broken or weak places are produced-effects which are preventedin the above-described machine by first starting the spindle by throwingthe belt Z onto the pulley K, and then starting the drawing-rolls byfurther shifting the belt so as to operate on both pulleys K K, the beltbeing as wide as the combined faces of the pulleys K K and thearrangement of pulleys and connections described permitting this action.

To assist the winding on, I place upon the spindle D, above the upperend of the bolster, a cup or disk carrier, V, (which may be of any ofthe forms shown in Figs. 5 to 11,) the yarn being conducted to thespindle from the traveler, when the latter is near its lowest positionover the edge of said carrier, or in contact with a shoulder or partthereof, as shown in Figs. 10 and 11. The yarn in passing from thetraveler to the spindle rubs'against the carrier, and is carried roundthereby as soon as the spindle begins to revolve, thus avoiding a suddentension, apt to result when the rotation of the spindle alone isdepended upon to start the yarn in motion, and which frequently causesthe yarn to break without starting the movement of the traveler.

The carrier may be fixed to the spindle, as shown in Figs. 7 and 9, orit may bear frictionally on the spindle or on ashoulder thereof, asshown in Figs. 9 to 12; and to prevent the slipping of the yarn tooreadily the carrier may be provided with notches or shoulders, so as topresent faces or bearings which insure the movement of the yarn as thecarrier begins to revolve, as in Fig. 11.

The device further serves as a means of underwinding the yarn when thering is carried to its lowest position prior to doffing the bobbin, theyarn then lapping round the carrier V, in which it is assisted by thenotches or bearings before described, and being broken between the copand carrier when the cop is removed, the end being thus retained readyfor a fresh bobbin.

In Fig. 4 is illustrated a modification in which the spindle D turns ina long step, and the tube on of the wharve D incloses the tube 6 of thestep, and the ring tis carried by a ring-rail. In this case the wharvehas an independent bearing, as before, so that no strain comes on thespindle.
